Hello Guys,
I have a question that relates to finding the depth of each element in a multidimensional array. I am trying to struggle with this but not able to come up with a good solution.
Any help will be appreciated
Here is the problem statement

Given a nested list of integers, returns the sum of all integers in the list weighted by their depth
* For example, given the list {{1,1},2,{1,1}} the function should return 10 (four 1's at depth 2, one 2 at depth 1)
* Given the list {1,{4,{6}}} the function should return 27 (one 1 at depth 1, one 4 at depth 2, and one 6 at depth 3)
I tried to create a array reference 

my $arrref = [
        [1,1,1,1],
        [1,1,
             [2,2]
        ],
        [1,
           [2,
              [3,3]
           ]
         ]
          ];

But then I was stuck in the approach that I need to take for incrementing depth as I go deep one level and decrementing it when I go up one level..
